pwhash is a password hashing library, relying on well known and trusted implementations of cryptographic hashing functions, making password hashing as simple as:

from pwhash import PasswordHasher

pwhasher = PasswordHasher.from_config_file("pwhashc.json")

hash = pwhash.create(u"password")
verified, new_hash = pwhasher.verify_and_upgrade(u"password", hash)
if verified:
    authenticate()
    if new_hash is not None:
        save_new_safer_hash(new_hash)

There is no reason to make password hashing more difficult or upgrading your hash function less seamless.
